Description
Technical field
The invention belongs to many metals resources comprehensive utilization techniques of lithium niobium tantalum, are related to a kind of full mud of many metals resources of lithium niobium tantalum and float
The method of the common enriching and recovering of choosing.
Background technology
China's lithium resource is rich in minerals, by 2008, explored lithium ore mining area（48% is that lithium niobium tantalum is comprehensive interior
Rawore bed）Have at 32, be mainly distributed on the ground such as Sichuan, Xinjiang, Jiangxi, Hubei, Henan.The single mineral deposit of spodumene Ore is few, altogether
Accompanying mineral deposit is more, the valuable mineral such as its normal association lepidolite, niobium-tantalum ore, beryl, and comprehensive reutilization value is big.Due to mesh
Front shortage advanced select smelting support technology, most domestic ore dressing plant have only reclaimed lithium, not to its intergrowth mineral thing synthetical recovery,
It is allowed to be lost in a large number in mine tailing, causes the serious wasting of resources.Because of spodumene and association Nb-Ta mineral disseminated grain size often
Differ greatly, synthetical recovery is often difficult using single recovery method.Then Nb-Ta mineral loses in a large number based on recovery lithium, with
Lithium minerals is then lost in a large number based on recovery niobium tantalum, therefore, lithium niobium tantalum polymetallic ore synthetical recovery difficulty is larger, carries out lithium niobium tantalum many
The research and development of metallic ore Comprehensive Recovery Technology are imperative.
For the lithium polymetallic ore of association niobium tantalum, more ripe traditional handicraft is that " gravity treatment-magnetic separation-flotation " combines work
Skill, gravity treatment can obtain qualified niobium tantalum concentrate, but not good to the recovering effect of spodumene, Li2O grades are reclaimed about 5.5% or so
Rate is about 70% or so or lower, and raw ore all carries out gravity treatment, and re-selection process amount is big, and beneficiation cost is higher.Its substantially flow process
Predominantly：Jing screens out size fractionated and carries out multiple gravity treatment after raw ore ore grinding, is enriched with Nb-Ta mineral from size fractionated, but by
Low in raw ore niobium tantalum grade, ore handling capacity greatly, needs repeatedly enrichment just to obtain high grade niobium tantalum concentrate, so not only needs
Multiple stage shaking table is wanted, and ore dressing intermediate products are more, and complex procedures, beneficiation cost is higher, and due to multistage shaking table operation amount of metal
Loss is more serious, affects the response rate of follow-up spodumene flotation.Simultaneously as in lithium niobium tantalum polymetallic ore, grade it is low and
The thin association tantalum niobium concentrate thing of disseminated grain size is larger with the lithium minerals particle size differences compared with coarse grain, and gravity treatment often sorts effect to narrow grade
Fruit is preferably poor to the minerals separation effect of particle size differences great disparity.Therefore, " gravity treatment-magnetic separation-flotation " process integration is adopted
The efficient synthetical recovery of various valuable minerals relatively difficult to achieve.
Be disclosed as 03 month 2008 No. 26, Publication No. CN101147888A, it is entitled " spodumene ore deposit dense media-
The Chinese patent literature of strong magnetic ore separation process ", discloses a kind of beneficiation method of spodumene ore deposit, and it mentions and adopts dense media
Ore dressing reclaims spodumene, but lithium uneven for valuable mineral disseminated grain size, that ore properties are complicated with high intensity magnetic separation process integration
Pyroxene ore deposit, is difficult to reclaim using heavymedia separation.Therefore, the technique is higher to grade, embedding cloth feature is simple, easily choosing spodumene
Ore has certain effect, and for Ore clay content is big, the lithium polymetallic ore more than valuable mineral species, the scope of application has one
Fixed limitation.
Therefore had using " the common enriching lithium niobium tantalum of flotation-strong magnet-gravity " technique recovery lithium, niobium tantalum resources excellent well
Gesture.By the common enriching lithium niobium tantalum resources of floatation process, lithium niobium tantalums as most as possible are made to enter in bulk flotation concentrate, then to mixed floating
Concentrate carries out high intensity magnetic separation and reselection operation, so greatly reduces the treating capacity of magnetic separation and gravity treatment, and gravity treatment milling ore grain
Degree narrow distribution, substantially increases the gravity treatment efficiency of separation.And the key of this Technology is efficiently to be total to enriching lithium niobium by flotation
Tantalum resources, altogether enriching lithium niobium tantalum needs that concentration ratio is big, metal recovery rate is high for flotation, could be follow-up strong magnetic and gravity treatment creation necessity
Favourable condition.
Publication date be on December 04th, 2013, Publication No. CN103418488A, a kind of entitled " association particulate niobium
The Chinese patent literature of the comprehensive recycling process of the lithium polymetallic ore of tantalum ", discloses a kind of beneficiation method of lithium polymetallic ore,
The beneficiation method uses " flotation-magnetic separation-gravity treatment " technological process, but the de slime flotation that the technique is adopted certainly will be caused necessarily
The loss of degree lithium, the scope of application equally has certain limitation.
The content of the invention
Present invention is generally directed to the deficiency that prior art exists in terms of common association niobium tantalum lithium polymetallic ore synthetical recovery, especially
It is that altogether bioaccumulation efficiency is not high for flotation present in " the common enriching lithium niobium tantalum of flotation-strong magnet-gravity " technique, and concentration ratio is low to be caused
Resources loss amount it is big and affect the problem of follow-up strong magnetic and gravity treatment, there is provided it is a kind of efficiently, economy, recovery index it is preferably complete
The method of the common enriching lithium niobium tantalum resources of mud flotation, is that " the common enriching lithium niobium tantalum of flotation-strong magnet-gravity " technique whole process is efficiently comprehensive
Reclaim lithium niobium tantalum resources to create favorable conditions.
